yeah, my yeast never expires before i use it. i freeze it too, so it stays fresh. AND i also proof it first, even though it’s the instant yeast that doesn’t need it. long ago, i had some dead yeast and my loaf wouldn’t rise. now i hate wondering if the yeast is good and risk wasting time and ingredients

I had yeast fail on some ciabatta bread. But it's hard to find a warm spot and my oven light was out (leave door ajar). It's been replaced now, still don't have any warm spot I can count on. Pan of hot water in closed oven maybe.

So you wouldn't change anything? Did you use the recipe I posted or another one? I don't know that I would like Chalah sweeter but lighter and a little yeastier might be ok. I think you need a good balance of sugar and yeast.

I usually proof, don't use it that much though.
